SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill requires @parity/product-sdk-contracts, @parity/product-sdk-chain-client, @parity/product-sdk-signer, and includes scripts (resource) and references (resource) components.

What problem does it solve?

This Skill solves the problem of interacting with smart contracts on Asset Hub, providing a simple and efficient way to manage contract operations and data retrieval.

Core Features & Use Cases

  • Contract Management: Manage multiple contracts with cdm.json manifests or ad-hoc contracts.
  • State Management: Perform read-only calls and state-changing transactions on contracts.
  • Integration: Seamlessly integrates with other SDK packages for a full Polkadot ecosystem experience.
  • Use Case: Build a decentralized application that requires contract interactions on Asset Hub, such as a marketplace or token management system.

Quick Start

To get started, create a ContractManager instance and use it to interact with a contract. For example, to read the count from a contract, use the following command:

const counter = manager.getContract("@example/counter");
const { value } = await counter.getCount.query();

FAQPage Schema
How do I interact with smart contracts on Polkadot Asset Hub?▼

To interact with smart contracts on Polkadot Asset Hub, use a ContractManager instance to handle contract creation, state retrieval, and transaction submission for Solidity and PolkaVM contracts.

What is the best way to manage multiple smart contracts in a Polkadot decentralized application?▼

The best way to manage multiple smart contracts in a Polkadot decentralized application is using a ContractManager to organize contracts via cdm.json manifests or ad-hoc contract definitions.

Do I need specific SDK packages to perform contract interactions on Asset Hub?▼

Yes, performing contract interactions on Asset Hub requires the @parity/product-sdk-contracts package alongside @parity/product-sdk-chain-client and @parity/product-sdk-signer for full ecosystem integration.

Can I execute read-only calls and state-changing transactions on Asset Hub contracts?▼

Yes, you can execute read-only calls and state-changing transactions on Asset Hub contracts by utilizing the state management capabilities provided by the ContractManager component.

Does the Asset Hub contract SDK support both Solidity and PolkaVM contracts?▼

Yes, the Asset Hub contract SDK supports both Solidity and PolkaVM contracts, allowing you to manage contract operations and data retrieval across both virtual machine environments.
